Mean curvature flow translators with prescribed ends

题目: Mean curvature flow translators with prescribed ends报告人: 孙奥（芝加哥大学）时间：2023年7月12日，15:30-地点：海纳苑2幢101室摘要: Mean curvature flow is the fastest way to decrease the area of surfaces. It is the model in many disciplines such as material science, fluid mechanism, and computer graphics. The translators are a special type of mean curvature flow soliton. They are the singular...

On Hadwiger’s covering functional for the simplex and cross-polytope

题目：On Hadwiger’s covering functional for the simplex and cross-polytope报告人：连艳陆（杭州师范大学）时间、地点：2023年6月28日10：30-12：30，海纳楼2幢203摘要：In 1957, Hadwiger made a conjecture that every n-dimensional convex body can be covered by 2^n translations of its interior. The Hadwiger's covering functional is the smallest positive number r such that K can be covered by m transla...
